Condinary battery having both of its poles at the top, all that is necessary is to connect the conductors 3S and 39 'to the terminals 40 and '41, the conductors being ofsufiicient length to permit this tobe done and then press downthe cover until the lower edge contacts with flange 16. The lamp may then be carried by handle 15 in either hand and the switch set at on or 01f position by a movement of the thumb'agzimst the extension 37.

When the contact has been moved so that itsend 35'passes under the inner end of contact 27'the following circuit is estab lished to light the lamp: battery 11, termi "nal 40, conductor 38, cover 12, socket 18, "lamp 21, contact 27, contaet29, pivot 30,

mnductor 39, terminal 41, batteryll. In

-' its off position the circuit is broken through I contacts 27' and 29 by moving contact 29 out of engagement with contact 27;

It will be observed, from the above description, that the operating mechanism is carriedehtirely by the'cover or flanged support, and that by projecting the base of the lamp within the confines of the flange of the support, the contactof the lamp is made Within said flange below the top of the support. Thus,the hood of the lamp can be-secured to.the outside of the flange, which" provides a very simple and inexpensive structure.

The invention is not to be understood as restricted to the details set forth, since these may be modified within the scope of the appended claimswithout departing'from the spiritahdscope of the invention.

Having thus described the invention what- We claim as new and desire to secure by Letters Patent. is: v

' 1. A device of the class described, comprising a dry battery having both of'its poles at one end, a lamp support of conducting material adjacent the pole end of said battery, an electric lampcarried by said support and in circuit therewith as to one of its terminals, a contact member insulated from said support and withwhich the other lamp terminal is electrically connected when inserted to position,a switch member on said support for controlling the circuit, and flexible electrical connections fixedly and detachably connected with the poles of the battery and electrically connected to said support and said switch member, respectively.

2, A device -ofthe character described,

comprising a dry battery, an electric lamp, a support provided witha downwardly proj'ecting annular flange, said lamp being removably fixed to said flange with its base lying within theconfines thereof, and electrical connections to said lamp fixed to said support within said "annular flange and whose free ends are adapted for fixed en gagement with the poles of said battery.-

3; A device ofthe character described, comprising a casing, a battery removably disposed therein, a cap for said casing pro vide'd with a' downwardly-projecting annu-' la'r flange, an electric lamp removably fixed to said flange with'its base lying within the confines thereof, and electrical connections fixed to-said 'capwithin said annular flange and'whose free ends are adapted for engagement with the poles of said battery and said lam JOHN J.
